PATENTEB HAYZS l97| SHEET 1 [IF 2 PATENTED W25 lsn SHEET 2 OF 2TYPEWRITER TABLE BACKGROUND OF THE INVENTION In the tables hithertoknown, steel frame components and wooden components, that is, table top,drawers and shelves, constitute coordinate parts all of which are joinedto form the finished table, whose rigidity and stability is the resultof the rigidity of the elements and their connection with each other.

FIELD OF THE INVENTION It is an object of this invention to provide atable in which the rigidity and the stability are derived from a steeltube frame which consists of several elements which can be builttogether to form various table lengths and on which various tableelements such as table tops, shelves and drawers can be mounted, so thatmany combinations and writing tables of different sizes and design canbe made.

SUMMARY OF THE INVENTION In accordance herewith the inventioncontemplates a writing table having a steel tube frame to which thereare attached elements such as table tops, boxes of drawers and shelfboxes, the frame being formed of two gable sections connected with eachother by at least two top girders serving to support one or more tabletops, one of the girders being located at the rear surface of the table,whereas the other one is located at a substantial distance from thefront surface of the table, and at least one longitudinal girder locatedat the rear surface of the table at a level corresponding to theunderside of a box of drawers, the said girders being connected with thegable sections by means of screws or similar means of attachment.

In a special, preferred embodiment, according to the invention, thereare attached to the two top girders of the frame, partly a comparativelythin table top, preferably of steel and serving to support thetypewriter, partly one or more table tops of wood or similar material,and means to dampen sound and vibrations between the girders and thetable top.

By this construction, there will be substantially. no transmission ofvibrations from an electric typewriter, placed on the thin table top, tothe whole table, which would involve inconvenient operating conditions.The design also embodies the advantage that the height from the floor tothe keyboard of the typewriter may be kept comparatively low.

The invention is also concerned with means for supporting and advancinga tape for a tape-controlled typewriter, in which the extra equipment isefficiently protected and does not introduce any inconvenience to theoperator since the tape spool and the driving means are swingable in ahorizontal plane and mounted beneath a portion of the table top adjacentthe typewriter.

BRIEF DESCRIPTION OF THE DRAWING Various embodiments of a typewritertable according to the invention will now be described with reference tothe drawing, in which:

FIG. 1 shows the steel tube frame of the table with a table top elementfor supporting a typewriter, viewed in perspective,

FIG. 2 shows a table top for the writing table according to FIG. I,viewed in perspective and on a smaller scale,

FIG. 3 is a section through a part of a top girder and the table top,viewed from the side and on a still larger scale,

FIG. 4 shows a part of a writing table, viewed in perspective, with atape feeding device, and

FIG. 5 is the same as FIG. 4 on a smaller scale and with the said deviceswung inwards.

The frame consists of two gable sections 1 and 2, each having two legs 3and 4 and two transverse bars 5 and 6. The legs rest on adjustable feet7. The parts of the gable sections may be joined by welding so that eachgable section forms a rigid unit.

The two gable sections are connected with each other by means of threelongitudinal girders, i.e., two top girders 8 and 9 and a longitudinalgirder 10 which is located at the rear surface of the frame and connectsthe legs 3 at a location between the floor and the top girder 8. Thegirders 8I0 are connected with the gable sections by means ofscrews I1.

Attached to the frame is a table top element or a table top 12 of atypewriter table, the said top 12 being formed of a comparatively thinsteel plate and attached to the top girder 9 and a transverse bar 9a bymeans of three screws 13, shown in FIG. 3. The screws are countersunk ina hole provided in the top 12 so that the head 14 of the screw is flushwith the table surface, and the screw extends through a sleeve 15 ofelastic, resilient material such as rubber. The sleeve has a tubularportion 16 extending through a hole in the upper wall of the top girder9, and it has further a disc-shaped portion 17 located between the saidwall and the underside of the table 12. At the lower end of the tubularmember 16 is attached a nut 18 by vulcanization, into which nut thescrew 13 is screwed.

When the screw 14 is screwed further into the nut 18, the nut will bedrawn upwards, by which the diameter of the tubular portion 16 will beincreased and its curved surface will be forced towards the inner wallsof the top girder 9. By this means a completely vibration and sounddamping connection is provided between the steel plate 12 and the topgirder 9.

On the said table 12, which is thus insulated from the table frame, isplaced a typewriter, and to prevent the table from moving laterally, theedge portions of the table top 12 may be bent upwards so as to form edgerails for guiding the typewriter.

As indicated by chain-dolled lines in FIG. 1, a box for drawers 19 canbe attached to the three girders 8l0 by means of screws 20 at one sideof the writing table. The drawer rests by its weight on the girder 10,so that it is capable of resisting a very heavy load. If desired, thedrawer may be placed at the other side, or there may be one at eitherside.

On either side of the table top 12 and on the rear side of the same areplaced wood table tops 21 (FIG. 2), retained by means of screws throughthe girders 8 and 9. The table top 21 is only shown by way of example,since it is possible to use a large variety of forms of table topelements in connection with the table top 12 of the typewriter table,and by disassembly several embodiments may be produced on the basishereof to suit different requirements of operation; further, bysubstituting the girders 8-10 by corresponding girders of a differentlength, tables of other dimensions can be made. Such modificationsrequire no expert skill and can be made by the user in a short time bymeans of a screwdriver.

The frame is of very great rigidity, and the top girder 9 is placed sofar back as not to be inconvenient to the operators legs which may bepositioned beneath the outwardly projecting portion of the table top 12,which can thus be arranged at a comparatively low level to give asuitable working height for the keyboard of the typewriter.

As will be seen from FIG. 4, there is a distance between the box ofdrawers l9 and the table top 21, and in the space thus provided ismounted a device for winding a tape denoted by 22. The said deviceconsists of a supporting plate 23 swingable in a horizontal plane arounda pivot 24 which is screwed into the box of drawers l9, and the devicecan thus be swung outwards into the position indicated in FIG. 4 andinwards into the position indicated in FIG. 5, which is the operativeposition.

On the supporting plate 23 there is mounted a tape roll 26 for rotationabout a vertical shaft 25, the tape 27 being passed over a vertical taperoller 28 and a horizontal tape roller 29, from which the tape,indicated by chain-dotted lines in FIG. 4, extends into position infront of the typewriter 28 as shown in FIG. 5 and hence into thetypewriter. As will appear from FIG. 5, the tape feeding device will notin its retracted position cause any inconvenience to the operator, andwhen a fresh tape is to be mounted or a tape to be removed, the deviceis readily accessible in the extended position according to FIG. 4.

On the plate 23 is attached a funnel or channel 29, which at its upperend has a flared inlet opening 30 which in the retracted position of thedevice is located beneath the punching tool of the typewriter, so thatcircular paper pieces punched from the tape will fall into the funnel 30and into the channel 29, which in the retracted position is located justabove a collecting box 30 attached to the table, so that the punchedpaper pieces are collected in the box 30.
